Rigid Transformation Rules Review

Determine where Point X' would be if you translated Point x 3 units left and 9 units down.

• (-5, -4)

• (-1, -7)

• (-4, -5)

• (-1, 5)

What is the angle of rotation for this counterclockwise rotation about the origin?

• 90°

• 180°

• 270°

• 360°

Triangle A is rotated 90° clockwise with the origin as the center of rotation to create a new figure. Which triangle shows the new location?

• A

• B

• C

• D

What type of rotation does this represent (from red to blue)?

• 270⁰ clockwise around the origin

• 360⁰ counter clockwise around the origin

• 90⁰ counter clockwise around the origin

• 180⁰ clockwise around the origin

Describe the rotation.

• Rotation 90^o counter clockwise around the origin

• Rotation 90^o clockwise around the origin

• Rotation 270^o counter clockwise around the origin

• Rotation 180^o counter clockwise around the origin

When a figure is translated, what is true? Select all that apply.

• The image has the same coordinates as the preimage.

• All the coordinates from the image have moved in the same direction.

• Corresponding segments are parallel.

• The image and preimage are congruent.

• The image is a different size compared to the preimage.

When a figure is reflected, what is true? Select all that apply.

• The line of reflection is the perpendicular bisector of corresponding vertices.

• Corresponding vertices are equidistant from the line of reflection.

• The image moves a specified distance to the right, left, up or down.

• The image and preimage are congruent.

• The image is a different size compared to the preimage.

When a figure is rotated, what is true? Select all that apply.

• Corresponding vertices are equidistant from the center of rotation.

• You need to know the angle of rotation, center of rotation, and the direction.

• The image flips over a specific line.

• The image and preimage are congruent.

• The image is a different size compared to the preimage.
